Which statement best describes how climate affects landscapes?

• A. Climate only affects rock color.
• B. Climate shapes landscapes by influencing vegetation and contributing to erosion through changes in precipitation and temperature.
• C. Climate has no impact on erosion.
• D. Climate only affects animal life.

Answer: (B)

Climate drives how landscapes form by controlling the amount and type of vegetation, the amount of water available, and temperature patterns that cause weathering and movement of material. The best statement captures that climate shapes landscapes through its effects on vegetation and erosion, which come from changes in precipitation and temperature. Vegetation, influenced by climate, helps hold soil in place and influences soil development, while different climates produce different erosion rates—more rainfall or intense storms can move more sediment and carve channels, and temperature affects processes like freeze-thaw cracking that break rocks apart. The result is landforms that reflect the prevalent climate, from desert surfaces sculpted by wind and scarce vegetation to lush valleys shaped by abundant water and active weathering. The other options miss the broader, interaction-rich way climate influences both living cover and the physical breakdown and transport of rock, so they don’t accurately describe how landscapes are shaped.
